SFP transceiver module BlueOptics SFP-BXU34-20KM-PA-BO 1250 Mbit/s

The BlueOptics SFP-BXU34-20KM-PA-BO is a single-mode fiber optic SFP transceiver module designed for 1000BASE-BX-U links with a maximum data transfer rate of 1250 Mbit/s. Housed in a metal casing with a silver finish and weighing 20 g, this module supports LC simplex connections and a link range up to 20 km. The transceiver implements a unidirectional wavelength pair (1310 nm receiver / 1490 nm transmitter) and conforms to MSA SFP mechanical and electrical specifications for interoperability with compatible networking equipment.

Advantages

This BlueOptics SFP transceiver offers standardized SFP interfacing and broad compatibility with devices that support 1000BASE-BX-U modules. The metal housing provides mechanical robustness while the module’s design and selected components target long operational life and high availability. Built to MSA guidelines, the transceiver is suitable for Ethernet and related high-speed optical applications up to 1.25 Gbit/s over single-mode fiber.

How to use

Insert the SFP module into a compatible SFP slot on the network device while the device is powered down or following the vendor’s hot-plug instructions. Connect an LC simplex single-mode patch cable between transceivers at each end of the link, ensuring transmit and receive fiber orientation matches the BX-U wavelength pair. Verify link status and speed in the device management interface. If available and supported by the host hardware, enable Digital Diagnostics Monitoring (DDM/DOM) to monitor supply voltage, laser bias current, output power, received power and module temperature for ongoing maintenance.

Recommendations

Use certified single-mode LC simplex patch cords and, where possible, test a sample module in your specific hardware to confirm software compatibility and DDM support. Avoid exposing the transceiver to excessive mechanical stress or contaminants on the fiber connectors; keep dust caps in place when the module is not connected. Follow the host vendor’s guidelines for supported transceiver models to ensure full functionality.
